DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator car weight detecting device, and more particularly to an elevator car weight detecting device capable of displaying a weight value in a car.

[0002]

2. Description of the Related Art In a conventional elevator car weight detecting apparatus, as shown in FIG. 4, an anti-vibration rubber 3 having a spring covered with rubber is disposed between a platform 2 supporting an elevator car 1 and a car floor 1A. And suppresses the impact when the car 1 starts and stops. This anti-vibration rubber 3 is used to store passengers and luggage in the basket 1
, The operating piece 4A of the microswitch 4 provided at a predetermined interval on the platform 2 below the center of the car floor 1A is depressed to operate the microswitch, and the passengers and the car in the car 1 become full. Was being detected.

[0003]

The above-mentioned prior art is for detecting the total weight of a passenger who has entered an elevator car and notifying whether or not the detected weight exceeds a predetermined load. there were.

However, with the recent development of the tourism industry,
The number of elevators that can be delivered to hot springs and resorts has increased, and there have been many requests from elevator passengers to be able to measure their weight when riding a car. There is a problem that the demand cannot be satisfied only by the elevator car weight detecting device.

[0005] It is an object of the present invention to provide an elevator car weight detecting device capable of measuring the weight of a person riding in an elevator car.

[0006]

In order to achieve the above-mentioned object, the present invention relates to a method for reducing the load on a car by the amount of shrinkage of a vibration isolating rubber provided between a platform supporting the car of the elevator and a car floor. A weight sensor for converting a load applied to the car floor into an electric signal, a converter for converting an output signal of the weight sensor into a weight value, and a side plate of the car. A display unit provided with an output signal of the converter, and a push button provided on the side plate for outputting a display signal to the display unit.

[0007] With this configuration, the weight is displayed on the display unit only when the push button provided on the side plate is pressed, so that the passenger in the car can know his / her own weight and his / her own weight. Is never known to others.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a partially cutaway perspective view of a car showing an attached state of an embodiment of an elevator car weight detecting apparatus according to the present invention.

In FIG. 1, a weight sensor is attached adjacent to an anti-vibration rubber 3 attached between a car floor 1A and a platform 2, and converts a distance between the car floor 1A and the platform 2 into an electric output. Differential transformer 5 has car floor 1
A two-digit digital display 6 and a push button 7 are provided on the side plate 1B of the car. A converter 8 is attached to the upper part of the car 1, and the converter 8 is connected to the differential transformer 5, the digital display 6, and the push button 7, respectively.

Next, the operation will be described.

Now, when a passenger enters the car 1, the car floor 1
The load is applied to A, and the rubber cushion 3 contracts, and the distance between the car floor 1A and the platform 2 is reduced. On the other hand, the differential transformer 5 converts the distance between the car floor 1A and the platform 2 into an electric signal and outputs the electric signal to the converter 8. The converter 8 obtains the difference between the input electric signals and obtains the difference. Is performed to convert the electric signal into a weight, and the calculated value is output to the display 6. Here, when the passenger presses the push button 7, the display 6 displays the calculated value output from the converter 8 for a predetermined time, for example, 5
Display for seconds.

As described above, since the passenger in the car 1 presses the push button 7 to display the weight on the display 6 for only 5 seconds, the weight can be known without being known to others.

Next, another embodiment will be described with reference to FIGS.

FIG. 2 is a perspective view of a main part of the car floor, and FIG.
FIG. 3 is a sectional view taken along line AA of FIG. 2.

2 and 3, a plurality of P tiles 1Aa1, 1Aa2... 1Aan are attached to the surface of the car floor 1A, and an iron plate 9 and a load cell are provided between the P tile 1Aa2 and the car floor 1A. The load cell 10 is attached to the converter 8.

The passenger who got into the car 1 has a P tile 1A.
When the user pushes the push button 7 while riding on a2, the weight of the passenger is displayed on the display 6 for 5 seconds.

As described above, only the passenger riding on the P tile 1Aa2 of the car 1 is measured and displayed.

[0019]

According to the present invention, the weight is displayed on the display only when the push button provided on the side plate is pressed, so that the passengers in the car can know their own weight,
Nobody knows their weight.
